PRINTING PAPER-HANGINGS.

Specification of Letters Patent No. 6,404, dated May 1, 1849.

To all whom t may concern:

Be it known that we, VILLIAM M. SHAW and EZRA GOULD, of the city ofNewark, in the county of Essex and State of New J ersey, haveA inventeda new and useful improvement on a machine for printing paper ornamentingthe walls of houses, oilcloth,

and for such like purposes; and we hereby do declare that the followingis a full clea and exact description.

lst. The nature of our invention consists in providing a drum with aneccentric rail or flange on the same, on which is placed or connectedwith it, the slide of a horizontal shaft, for the purpose of giving anintermittent horizontal motion to the frames in which the blocks aresecured that make the impressions on the paper; also in providing avibrating reciprocating catch bar to take the paper when printed fromunder the block, drawing it forward on a transverse table, thus makingthe machine self feeding.

2d. The nature of our invention further consists in attaching theplatens of the block plates to standards connected to the frames inwhich the said platens are placed by coiled springs which spring up boththe blocks and platens from the paper after the impression is made.

3d. It further consists in providing spring pistons, passing verticalthrough guide eyes attached to suspended jointed arms, to be operated bycams on an upper revolving shaft, which cams press down regularly thespring pistons on the top of the platens to make one block impress thepaper with color, and the other receive color from a color-sieve, (whichis the technicalterm for t-he color or paint cushion,) the pressure ofthe cams of the pistons being regular to coincide with the period ofintermission in the motion of the sliding shaft below, to make theimpression on the paper at the exact period.

To enable others skilled in the art to make and use our invention, wewill proceed to describe its construction and operation reference beinghad to the accompanying drawing making a part of this specification, inwhich- Y Figure l is a longitudinal elevation. Fig. 2 is a horizontalsection, showing how the main reciprocating shaft F, is attached to, andcommunicates motion to the platens and the machinery7 that feeds andvshifts the paper. Figs. 3, 4 5 and 6, are views of the brushes andbrush plates. Fig. 7, is a side section of the vibrating lever thatoperates the catch which moves the printed paper from the blocks.

The same let-ters indicate like parts on all the figures.

A is the frame, built of solid materials in any known way.

G, is a large drum made of wood or metal.

Z is a metal ridge or rail secured to the drum and made to extend in acurved direction from end to end of the said drum, but with a part ofthe said rail a, a extending at the ends of the drum at right angles toone another like a rim about one sixth of the circumference of the ends.

We do not confine ourselves to this proportion of the said rail on theends of the drum, as it can be varied with the gearing that moves therevolving shaft H. This eccentric rail drum is suspended in the frame bya shaft which revolves in proper bearings therein. This drum is drivenby a pinion X on the cross shaft P, Fig. l, which gears into a bevelwheel Q on the inside end of the drum shaft F, is the shaft which movesthe block frames.

This shaft is formed with a common box slide head (g) which embraces Z,which moves it, and it is guided in la horizontal direction between twoside 4guide rails f, f, when the drum therefore is revolved, the shaftF, will be moving backward or forward, except when a, a is pressingunder (g) for t-he jaws of (g) are vso formed as to allow a, a to slidethrough them, at which time the shaft F, is stationary, and thus by therail on the drum a horizontal intermittent motion is given to the shaftF. This shaft is connected to the block frame (it, la) by a screw orbolt.

The block frame (one for each block), is composed of-four square piecesof metal or it may be cast all in one piece with angular corner piecesand upright standards, j. The block frames are made so as they shallembrace and slide on a rail B, B, on each side of the frame to keep theblocks direct, steady and true in their motion. The two block frames areconnected together by an arm in the middle and they have corner blocksthat embrace the rail B, but as this plan of guiding blocks or shafts iswell known, it need not be further described. The rail B B dips orinclines at each end B2 B2 above two color boxes E, E, which hold thecolor'to supply the brushes W', W, D, D are two blocks secured to theplatens (n) by screws. Each platen consists of four arms (m) (m) with asolid center block and two braces through which pass the screws thatsecure the block D, to the platen. The ends of the arms of the platensare formed with a wedge grooved in each to allow the platen to slide upand down on wedge projections formed on the inside of (i) as seen inFig. 2.

The platens and blocks are separate parts from the frame (h) but made tofit snugly therein, and they are (the platens) kept up some distancefrom one to two inches above the surface of the transverse table and thesieve T by coiled springs (p) attached to the standards, j, j. Tograduate the pressure on the coiled springs, we insert metal orotherblocks between the springs andthe standards, but these blocks are .notrepre sented in these drawings. W, WV are two brushes which are madeabout the breadth of the seive T. These brushes are attached to theblock frames by joints made in the usual manner and bars Y, Y.

The brushes are formed by securing the bristles between two metal platesas represented by Figs. 3, 4C, 5 and 6, the bristles being secured bythe platesv being screwed tightly together by screws. Each brush isprovided with two friction rollers or wheels (r, 13) which move on thetop of the inclined rail B2 B2 to allow the brushes to dip into thecolorboxes E, E, and when the brush is drawn out of the trough it is carriedalong the surface of the sieve T supplying it regularly with color forthe return of the block D. v

During every revolution of Gr, the block frames and blocks are movedonce backward and forward, with two intermissions in the motion when a,a, is passing under (g). The intermissions occur when the block ismaking the impression on the paper, which is performed at that period orperiods by the spring pistons being pressed down upon the center blocksof the platens by cams on the revolving shaft H. This shaft H issuspended in proper bearings o-n the frame, and it has four cams securedon it (u u) (u2 u2). These cams are the same in principle as cranks andeach has a friction pulley (4) on its end to lessen the friction whenthe cams are in contact with the tops of the spring pistons. When theshaft lH revolves the ends of the cams are brought in contact with thespring pistons 31, 32 during the intermission of the motion of F, andwhen the block, is above the paper to receive the impression and thesaid cams force down the spring pistons upon the center blocks 2, 2 ofthe platens and make the impression on the paper.

Two cams u u placed opposite to one another, are fixed on the shaft Habove the block that prints, and only one cam is placed on the shaftabove the sieves to get the color on the blocks, therefore twoimpressions are made during the intermission for every revolution of H.When the spring pistons are relieved from the pressure of the cams 3132, the platens rise with the blocks from the paper and color sieve bythe springs On the top of each piston there rests the end of a jointedarm secured to the side of the frame.

The end of each arm is of a concave form to allow the friction rollersto roll therein. The heads of the spring pistons however may be soformed as to obviate the use of the jointed arms. O, O, O, are the guideeyes through which and in which the spring pistons work. They are placedexactly above the point to make the end of t-he piston press on thecenter block 2 of the platen during the intermission of the motion of F.

Then the block risesrfrom making the impression on the paper, the paperso irnpressed is drawn forward on the transverse table, and otherunprinted paper is then drawn below the block to the exact pitch toreceive the impression from the next block. This is accomplished asfollows: The mot-ion of the paper must be intermittent to coincide withthe motion of the printing block; the slide catch therefore which movesthe paper has an intermittent vibratory motion.

The paper to be printed is placed below the guide plates C, C, whichhave slots and set screws for guiding in various widths of paper. Thepiece of paper is extended under the block to be below the catch slideJ1 J2. These catch slides are cross bars with 105 slides I I, which moveon and are guided backward and forward on slide rails.

The catches are operated as follows: N, is a short arm secured by apivot to one of the block frames and attached by a pivot to the 11'0oscillating angular lever M, which is secured by a pivot to'a metallicblock or plate 8, fixed on the table as represented by set screws. V, isa connecting rod attached by a pivot K, to M, the oscillating angularlever, 115 and to a rocking head or bar L, (as represented in Fig. 7This rocking head is connected to IJ2 by a center pin on which itvibrates and one of the rockers passes through a slot in J1. Thereforewhen the block 120 frames are moved, the slides I, I, and the catches J1J2 will be moved likewise; but when the slides are moving toward theblock frame, the rocker head is thrown back and Y the paper is releasedfrom the catch bar J1, 125 but whenever the slides move forward again,the rocker head vibratesvforward catching the paper and carrying itforward on the table from the block; and so on continuously. The screwg, on L, is for regulating the dip or rock of L, as may be desired tomake the paper be caught by J1 to suit truly to the pitch of the block.

The shaft H is moved by cog Wheel gearing. R1 is fixed on the shaft7 b,it gears into R2 another cog wheel on a` side shaft and it gears into R3on the shaft H. This gearing is just made to connect H above F, but witha side intermediate Wheel R2 to clear F, a common manner of arranginggearing. During every revolution of G, two impressions are made o-n thepiece of paper, the blocks are supplied With color, the sieves fed Withthe same bythe brushes, the pressure is regularly applied by the cams onthe revolving shaft and the paper is regularly taken away and fed in tobe printed, a combination and arrangement of various parts, all Workingharmoniously from the pinion X to accomplish in one machine the selffeeding and coloring and printing operation in this diliicult art.

lVhat We claim as our invention, is-

1. The combination of the platens With the to keep up the blocks fromthe face of the l table, and to allow the said blocks to be pressed downon the paper, and color sieves, substantially as described.

2. `We also claim the arrangement of the cams on the revolving shafts,in combination with the springs, pistons in the guide eyes 0, 0, o, topress down the platens during the intermission of the motion of theblock iframes, substantially as described.

3. lWe also claim the combination of the catch bars J1 J2 With therocker L, and t-he connecting rod V, and oscillating angular lever M,and the arm N, connected with the block frame, to take the printed paperfrom under the block, and bring forward the unprinted paper to receive'the next impression, substantially as described.
